Default Having same issue here

Having the same issue.

Whenever I try to launch Java GUI apps (java 1.8) while connected to DisplayLink it crashes.
java.lang.NullPointerException
at java.awt.Window.init(Window.java:497)
at java.awt.Window.<init>(Window.java:537)
at java.awt.Frame.<init>(Frame.java:420)
at java.awt.Frame.<init>(Frame.java:385)
at javax.swing.SwingUtilities$SharedOwnerFrame.<init> (SwingUtilities.java:1758)
at javax.swing.SwingUtilities.getSharedOwnerFrame(Swi ngUtilities.java:1833)


./bin/java -version
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)

If I unplug the DisplayLink then start, the app comes up without any issue and will continue to run even after I plug DisplayLink back in.
